Well just like you said everybody have their reasons why they joined this forum and the reason why someone joined this forum shouldn't be anyonecase or shouldn't be anyone concern but the most important thing is getting that thing which brought you here. You said that some people joined the forum because of signature campaign which is something I can't say it's a truth or not. I believe that if someone join this forum for any reason that is outside what this forum is meant for the person will not find it funny any longer and that can result to so many things that I can't really tell for now.
